STEP-BY-STEP SUPPLY METHOD OF LUBRICATING COOLING PROCESS AGENTS Russian patent published in 2012 - IPC B24B55/02 

FIELD: machine building.

SUBSTANCE: lubricating cooling fluid (LCF) is supplied to the processing zone at stages of cutting-in (τ₁) and removal of the main part of allowance (τ₂). At sparking-out stage (τ₃), solid lubricant (SL) is applied in molten state to quickly-rotating grinding wheel (GW). Supplies of LCF and SL are separated in time by introducing the stage of dry allowance removal (τ₄). Then, LCF and GW supplies for cutting-in are stopped at the last stroke of GW at stage (τ₂) of grinding cycle, and allowance is removed only due to tightening in the process system of the machine. This allows preventing perturbation of contact temperatures at dry grinding during time (τ₄) and increasing adhesion of SL to abrasive material by its dehydration.

EFFECT: vibrations in the process system are reduced; the time of working cycle is shortened and quality of completed parts is improved.
